In Reply to: What parts do I need to add alarm to my 92 525i? posted by Byron on October 26, 2000 at 23:33:50:
You could use the BMW stock alarm and plug it into the prewired alarm harness, or you can find an Alpine 8040, 8080, 8020, etc. They should all work. as they are the same as the stock alarm. I think the 8020 is the one that they used. If you get a stock alarm and need a remote, the Alpine 8440 will work great.
